Are there any specific guidelines or rules for using special characters in PHP to avoid confusion or errors?

To avoid confusion or errors when using special characters in PHP, it is important to properly escape them using backslashes (\). This ensures that the special characters are interpreted correctly by the PHP parser and do not cause any syntax errors. 

// Example of properly escaping special characters in PHP
$string = "This is a string with a special character: \$";
echo $string;
